The only known multidigit palindromic Woodall prime.
Sexy primes are such that n and n + 6 are both prime. The pair (383, 389) for example.
The first multidigit palindromic prime to appear in the decimal expansion of  . [Wu]
The sum of the first three 3-digit palindromic primes. [Vouzaxakis]
383 is the smallest p(n) such that the continued fraction expansion of [p(n)+sqrt(p(n+1))]/p(n+2) has a prime number of coefficients in its periodic portion. [Rupinski]
The smallest prime which can be represented as sum of a prime and its reversal (241 + 142 = 383). [Gupta]
383 = 6*2^6 - 1. [Noll]
The smallest palindromic Pillai prime.
Together with 191, this prime forms a palindromic Sophie Germain pair: i.e., 2(191)+1 = 383. Less known is the fact that 383 divides the Mersenne number 2^191-1. [De Geest]
383 = prime(3*8*3) + sigma(3+8+3). Note that 383 is the earliest number (coincidentally prime) with this property. [Firoozbakht]
The smallest prime of the form 383*2^n+1 is titanic.
383 is the product of the even digits minus 1. [Silva]
An aqueous solution of hydrochloric acid boils at a higher
temperature than pure water and reaches a maximum boiling
(or azeotropic) point of 383 K. [Beedassy]
The sum of three consecutive balanced primes (53+157+173). [Silva]
