The only prime subscript of a triangular number that is also a square pyramidal number : 1 + 2 + 3 + ... + 11 + 12 + 13 = 1^{2} + 2^{2} + 3^{2} + 4^{2} + 5^{2} + 6^{2}. [Beedassy] The prime whose square is equal to the sum of squares of all digits in which primes end: 13^{2} = 1^{2} + 2^{2} + 3^{2} + 5^{2} + 7^{2} + 9^{2}. [Beedassy] The smallest prime that when concatenated to its Collatz sequence (13 > 40 > 20 > 10 > 5 > 16 > 8 > 421) inexorable ending 421 forms another prime: 13421. Note that a reverse concatenation also yields a prime (12413). [Beedassy] The smallest prime that is equidistant by a prime (3) between the sum of squares of its digits (1^{2} + 3^{2}) and the square of the sum of its digits (1 + 3)^{2}. [Beedassy] In the great ancient Indian epic Mahabharata, the righteous Pandava clan, after losing their staked kingdom through deceit in a game of dice schemed out by the envious Kaurauva cousins, were forced to undergo 13 years of exile. [Beedassy] Religious scholar A. C. Bhaktivedanta Swami Prabhupada gives the equivalent length of a yojana as approximately 13 kilometers. [Beedassy] In chess, a Bishop controls a maximum of 13 squares of a given color. [Beedassy] The 13 enddigits of the overwhelmingly gigantic Graham's number (g_{64}) form a second prime concatenation: 7262464195387. [Beedassy]
