Antisigma(n) = A024816(n) = the sum of the nondivisors of n that are between 1 and n.
Conjecture: also numbers k such that antisigma(n) = antisigma(m) = k has solution for distinct numbers n and m. - Jaroslav Krizek, Nov 10 2013
EXAMPLE
36844389 is in the sequence because 36844389 = antisigma(8585) = antisigma(8586).
