Collection of interesting residues

Viliam Furik · 2021-01-09, 02:12

Somewhere in the forum is a thread about interesting residues. I couldn't find it, so here is my one interesting residue:

E5D4D56490DEAD8E (2399387)

An interesting exercise is to eval the probability of such 4-letter occurrence under (more or less adequate) assumption of random nature of residue values' distribution.

Other than that, this is a fairly popular initialization value (to detect memory leaks in one's code or similar) v = 0xDEADBEEF.

Yes, I have seen similar things in the aforementioned thread. But still, it's funny to see it in one's own results.

A quick search of some old residues reveals this:

3453*2^380518-1 : LLR Res64: 09BDEADBEE8598F7
59095*6^143189-1 : RES64: B34A39EA4CC0E9F3. OLD64: 19DEADBEE642BDD8

48047305725*2^112274-1 : LLR Res64: 2906942E2DEADBED

190285095*2^6399-1 : LLR Res64: F975AE8DEADBEAFF

Test them with LLR for this data file:

Code:

1:M:1:2:258
3453 380518
48047305725 112274
190285095 6399
1:M:1:6:258
59095 143189

Thank you!

Well, it was bad...
