[QUOTE=gd_barnes;255306]Reserving S841 to n=25K.[/QUOTE]

Suggestion (from old times): For these, try the speed of tests in bases 5 and 29, resp.

Example:
[CODE]852*625^15007-1 is composite: RES64: [E5A0E1CE02AF5DAB] (32.6333s+0.0003s)
852*625^15013-1 is composite: RES64: [BA3CA43E48807023] (32.5645s+0.0004s)
852*625^15014-1 is composite: RES64: [48B305268B6A1153] (32.6947s+0.0005s)
852*625^15023-1 is composite: RES64: [CCC088F9BE01EC40] (32.5024s+0.0004s)

vs. (an equivalent task)

852*5^60028-1 is composite: RES64: [E5A0E1CE02AF5DAB] (15.5125s+0.0003s)
852*5^60052-1 is composite: RES64: [BA3CA43E48807023] (15.5065s+0.0004s)
852*5^60056-1 is composite: RES64: [48B305268B6A1153] (15.4888s+0.0005s)
852*5^60092-1 is composite: RES64: [CCC088F9BE01EC40] (18.0302s+0.0004s)
