COMMENT

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 A for this case see A147643.

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.
