+ The larger of only two 3-digit primes that remain prime when inserting one, two or three zeros between each digit, i.e., 50707, 5007007, 500070007 are primes. The other such prime is 131. [Loungrides]

+ The smallest prime that can be expressed as sum of powers with the even digits as bases and exponents, i.e., 0^6+2^8+4^4+6^0+8^2 = 577. [Loungrides]

+ The larger of only two primes p, smaller than a thousand, such that p and p^3 have the same sum of digits. The other is 487. [Loungrides]

+ The only 3-digit prime p such that 3p^3 contains three consecutive zeros in its decimal representation, i.e., 3*577^3=576300099. [Loungrides]

+ The 17th Pierpond prime, (form 2^u*3^v+1), is the largest prime-digit Pierpond prime, i.e., 577 = 2^6*3^2+1. [Loungrides]
