COMMENTS
A242962(n) = (n*(n+1)/2) mod antisigma(n) = A000217(n) mod A024816(n); where A000217(n) = triangular numbers, A024816(n) = sum of numbers less than n which do not divide n.
Complement of A243118.
a(n) = A002191(n+1) for n >= 5; where A002191 = possible values of sigma(n).
EXAMPLE
0 is in the sequence because there is a number m such that A242962(m) = 0; m = 3.
