EXAMPLE

Applying the map as defined in A076340, A076341:

A005117(40)=65=5*13=(4+1)*(12+1) -> (4,1)*(12,1) = (4*12-1,12+4) = (47,16), therefore a(40)=16 and A076347(40)=47.

CROSSREFS

Real part = A076347, A070750, A076344, A076350, A076352.

Sequence in context: A264969 A320301 A061916 * A263835 A113310 A081653
