How high a number (n) has been searched for Catalan pseudoprimes?

edit

In stating that "The only known Catalan pseudoprimes are: 5907, 1194649, and 12327121", it would add a lot more context if an upper bound was given as to how high a number that this has been tested to. Like for example "The only known Catalan pseudoprimes less than ?????????? are 5907, 1194649, and 12327121" — Preceding unsigned comment added by 193.82.231.103 (talk) 02:32, 17 October 2024 (UTC)Reply
