In A027623 (number of rings with n elements), I noticed that for p prime,
a(p) = 2 and a(p^2) = 11 seem to be true. However, for p^3, we have a(8) =
52 while a(27) = 59, so a(p^3) depends on p. Then I found this enticing
tidbit:
The paper by Antipkin/Elizarov also gives the number a(p^3) of
rings of
order p^3. - Hans H. Storrer (storrer(AT)math.unizh.ch), Sep

the paper being the cryptic
V. G. Antipkin and V. P. Elizarov [Math. Rev. 84d:16025]
If A027623(p^3) were in the OEIS, it would start 52,59,... But no such
sequence exists in the OEIS.
