FORMULA

a(n)=A057809(n+1)-A057809(n)

EXAMPLE

Large differences arise between max term in a cluster and least one in the next cluster of A057809. While small entries obtained as differences inside a cluster.

E.g.:...,21,6467079011,198,22,110,132,22,242,66,17541629593,23,... shows by first differences the transition from the 21st cluster to 23rd solution-set over the 22nd-set with multiples of 22.

First cluster is empty, while 11-th contains one term (see A038227).
