Not typos, exactly, but the convention in the OEIS is to use 
parentheses for indexing into sequences, not brackets.  So that should 
really be:

"The quotient A024916(n)/a(n) = SummatorySigma/SummatoryTotient as n 
increases
seems to approach Pi^4/36 or Zeta(2)^2 [~2.705808084277845]. - Labos E.

There are 3/2 typos in 
http://www.research.att.com/~njas/sequences/A002088:
"The quotient A024916[n]/a[n] = SummatorySigma/SummatoryTotient as n 
increases
seems to approach Pi^2/36 or Zeta(2))^2 [~2.705808084277845]. - Labos 
E.
(labos(AT)ana.sote.hu), Sep 20 2004"

should read:

"The quotient A024916[n]/a[n] = SummatorySigma/SummatoryTotient as n 
increases
seems to approach Pi^4/36 or Zeta(2)^2 [~2.705808084277845]. - Labos E.
