Different squares on an n X n lattice

[David Wilson]

I recommend these modifications.  Please review:

========================================================================
Replace:

%C A002415 Also number of squares which can be drawn using points of an n X 
n square array as corners.

with

%C A002415 a(n) = number of squares with corners on an n X n grid.  See also 
A024206, A108279.

========================================================================
Add:

%C A0024206 a(n) = number of squares with corners on an n X n grid, distinct 
up to translation.  See also A002415, A108279.

========================================================================
Add:

%S A108279 
1,3,5,8,11,15,18,23,28,33,38,45,51,58,65,73,80,89,97,107,116,126,134,146,

%N A108279 a(n) = number of squares with corners on an n X n grid, distinct 
up to congruence.
%Y A108279 See A002415, A024206.
