1,1

If ABC conjecture is true this sequence is finite.

a(4) is recent record of L(a,b,c) in general.

For numbers B for this case see A147641.

For numbers C for this case see A147642.

Function L(A,B,C) and A<B<C will be Log[C]/Log[rad[ABC]]

where function rad[ABC] is product of distinct prime divisors A*B*C and A,B,C don't have anyone that same prime divisor.

Successive records for L(A,B,C) see A147302.

A085152, A085153, A147298-A147307, A147638-A147643.
