124 is the sum of eight consecutive primes (5 + 7 + 11 + 13 + 17 + 19 + 23 + 29). It is a nontotient since there is no integer with 124 coprimes below it, it is an untouchable number since there is no integer whose proper divisors add up to 124.

In base 5 it is a repdigit and in base 8 it is a Zuckerman number.
