[seqfan] Re: Cumulative multiplication

[Max Alekseyev]

There are no other terms below 10^300.
The sequence is subsequence of A007602 and likely of A128606 and A257554.
The latter (which intersection of the former two) itself is likely finite.
Below 10^300 it has 66 terms with the largest containing just 46 digits.

Regards,
Max
