Cardano Triplets

Statement only · SolvedOriginal problem ↗

A triplet of positive integers (a,b,c) is called a Cardano Triplet if it satisfies the condition:

a+bc3+abc3=1

For example, (2,1,5) is a Cardano Triplet.

There exist 149 Cardano Triplets for which a+b+c1000.

Find how many Cardano Triplets exist such that a+b+c110000000.
