@bloodripelives I'm a big fan of 7. yes it's a popular choice, but it's popular for a reason! much literary history makes use of it, as well as 3, and they both construct such satisfying groups
@soph_sol seven and three also great ones! Need to show some love to neglected friends like 7177
@bloodripelives so true! just because 7177 doesn't have special properties like being a sexy prime or super-prime or happy prime or lucky prime or any of the other named varieties of prime is no reason to ignore it!
@soph_sol @bloodripelives i do think primes are particularly satisfying when all of their digits are also prime (though then of course we’ll have to debate whether or not 1 counts as prime for this purpose)
@soph_sol @bloodripelives two and zero are also odd, but they’re all odd in such different ways!
