1, 2, 4, 8, 15, 16, 30, 32, 60, 64, 120, 128, 143, 225, 240, 256, 286, 450, 480, 512, 572, 900, 960, 1024, 1144, 1800, 1920, 2048, 2145, 2288, 3375, 3599, 3600, 3840, 4096, 4290, 4576, 5183, 6750, 7198, 7200, 7680, 8192, 8580, 9152

Table of n, a(n) for n=1..45.

Example

Applying the map as defined in A076340, A076341:
120=5*3*2^3=(4+1)*(4-1)*2^3 -> (4,1)*(4,-1)*(2,0)^3 = (4*4+1,4-4)*(8,0) = (136,0), therefore A076340(120)=136 and A076341(120)=0;
130=13*5*2=(12+1)*(4+1)*2 -> (12,1)*(4,1)*(2,0) = (12*4-1,12+4)*(2,0) = (94,32), therefore A076340(130)=94 and A076341(130)=32, hence 130 is not a term.
