A242486 Numbers n such that A242480(x) = n has no solution. 6

%I #6 May 29 2014 12:08:09

%S 1,4,10,14,22,26,34,36,38,46,48,50,58,60,62,74,82,84,86,90,94,98,106,

%N Numbers n such that A242480(x) = n has no solution.

%C A242480(n) = (n*(n+1)/2) mod n + sigma(n) mod n + antisigma(n) mod n = A142150(n) + A054024(n) + A229110(n) = (A000217(n) mod n) + (A000203(n) mod n) + (A024816(n) mod n).

%C All values of a(n) are even for n > 1. Complement of A242485.

%e 14 is in the sequence because there is no x whose A242480(x) = 14.

%Y Cf. A242480, A242481, A242482, A242483, A242484, A242485.
