Even numbers of circ causes weird spacing
I noticed when trying to make a string of 6 circ
symbols that the last one is closer to the one beside it than the rest of them, after playing with it for a while it looks like an even number (greater than 2) of circ
causes this, how can I fix the spacing so it is even?
Example:
documentclass{article}
begin{document}
1 circ: $circ $
2 circ: $circ circ $
3 circ: $circ circ circ$
4 circ: $circ circ circ circ$
5 circ: $circ circ circ circ circ $
6 circ: $circ circ circ circ circ circ $
7 circ: $circ circ circ circ circ circ circ $
end{document}

From the TeXbook (page 187, solution on page 326)
Exercise 19.7
B. L. User tried typing ‘eqno(*)
’ and ‘eqno(**)
’,
and he was pleased to discover that this produced the equation numbers
‘(∗)’ and ‘(∗∗)’. [He had been a bit worried that they would come out
‘(*)’ and ‘(**)’ instead.] But then a few months later he tried
‘eqno(***)
’ and got a surprise. What was it?
When you type an asterisk in math mode, plain TeX considers
*
to be a binary operation. In the cases ‘(*)
’ and ‘(**)
’, the
binary operations are converted to type Ord, because they don't appear in
a binary context; but the middle asterisk in ‘(***)
’ remains of type Bin.
So the result was ‘(∗ ∗ ∗)’. To avoid the extra medium spaces, you can
type ‘eqno(*{*}*)
’; or you can changemathcode`*
, if you never use
*
as a binary operation.
It doesn't matter if we're in an equation number (eqno
); the main issue is math mode where the behavior shows. Since circ
is a binary operation symbol just like *
, you get the same.
If you want evenly spaced circ
symbols you can use
{circ};{circ};{circ};{circ}
Even better, define a suitable command:
documentclass{article}
usepackage{xparse}
ExplSyntaxOn
NewDocumentCommand{circs}{m}
{
ensuremath
{{
{circ}prg_replicate:nn { #1 - 1 } { ; {circ} }
}}
}
ExplSyntaxOff
begin{document}
$circs{1}$
$circs{2}$
$circs{3}$
$circs{4}$
$circs{5}$
$circs{6}$
$circs{7}$
end{document}
Great explanation (and excercise too)!

When you issue showcirc
you'll see it defined as mathchar"220E
. The first number in this definition points to the intrinsic "format" of the character. 2
denotes a binary operator which has a specific spacing around. So, circ
is considered a binary operator and therefore expects operands on either side. Odd-numbered circ
s show better alignment as they supply "operands" on either side (barring accommodation for uniform spacing around consecutive circ
s):
documentclass{article}
begin{document}
1 circ: $circ$
2 circ: $circ circ$
2 circ: $circ circ {}$
3 circ: $circ circ circ$
4 circ: $circ circ circ circ$
4 circ: $circ circ circ circ {}$
5 circ: $circ circ circ circ circ $
6 circ: $circ circ circ circ circ circ$
6 circ: $circ circ circ circ circ circ {}$
7 circ: $circ circ circ circ circ circ circ$
end{document}
If you just want to list a number of circ
s with the correct spacing, consider adding a empty math group at the end when using an even number of circ
s. Alternatively, use {circ}
or mathord{circ}
to avoid the surrounding space; mathord
turns its argument into a math ordinal.

When you issue showcirc
you'll see it defined as mathchar"220E

denotes a binary operator which has a specific spacing around. So, circ
