The sort sequence for A130274 is as described in A129305.
|
|
EXAMPLE
|
Consider the five primes {2, 3, 5, 7, 11} then create the subsets {2,7} and {3,5,11} which corresponds to the Murasaki diagram showing the first and fourth objects connected and the second,third and fifth connected.
Calculate A000040(2*7-1) times A000040(3*5*11-1) = A000040(13)*A000040(164) = 41*971 = 39811. Therefore 39811 is a member.
