Primes are exciting, like 149.

I like 149 ...
149 is the 35th prime number, and with the next prime number, 151, is a twin prime, thus 149 is a Chen prime. 149 is a strong prime in the sense that it is more than the arithmetic mean of its two neighboring primes. 149 is an Eisenstein prime with no imaginary part and a real part of the form .
Given 149, the Mertens function returns 0. 149 is a tribonacci number, being the sum of the three preceding terms, 24, 44, 81.
149 is a strictly non-palindromic number, meaning that it is not palindromic in any base from binary to base 147. However, in base 10, it is a full reptend prime, since the decimal expansion of 1/149 repeats
