%N Number of divisors associated with the cyclic cases within the n-th group of least prime signatures.
%F a(n) = A074141(n) - 2* A074141(n-1) for n > 0 and a(0) = 1
%e The number of divisors doubles each time we create a new "matching" partition by appending "1" to a given partition. Therefore we may write
%e ..1..0..3..4..14..18..65..82..253..378..953...
%e + ...2..4.14..36.100.236.602.1368.3242.7240...
%e = 1..2..7.18..50.118.301.684.1621.3620.8193...
%Y Cf. A074141.
