To extend A018216 Maximal number of subgroups in a group with n elements

[Maximilian Hasler]

also, the

%F A018216 (C_2)^m has A006116(m) subgroups, so this is a lower bound
if n is a power of 2
               (e.g. a(16) >= 67). - njas, Dec 01 2007

rather belongs to A061034 ; since we already have (fix ")" -> "}")

%F A018216 a(n)=Maximum of {A061034(n), A083573(n)). - Lekraj Beedassy
(boodhiman(AT)yahoo.com),  Oct 22 2004

both of these sequences {A061034(n), A083573(n) } provide a lower
bound for A018216.
