Sixty is the sum of a pair of twin primes (29 + 31), as well as the sum of four consecutive primes (11 + 13 + 17 + 19). It is adjacent to two prime numbers (59,61). It is also the smallest number which is the sum of two odd primes in 6 ways.
Need mods? I'm available for mod4mod. Unless the map you want modded is either Yousei teikoku, karen or denkare cuz then i'll gladly do it without asking for a mod.
