The previous is forty-one, with which it comprises a twin prime, and the next is forty-seven. 43 is the smallest prime that is not a Chen prime. It is also the third Wagstaff prime. 43 is the fourth term of Sylvester's sequence, one more than the product of the previous terms (2 × 3 × 7). 43 is a centered heptagonal number. Let a(0) = a(1) = 1, and thenceforth a(n) = (a(0)2 + a(1)2 + ... + a(n-1)2) / (n-1). This sequence continues 1 1 2 3 5 10 28 154... . Amazingly, a(43) is the first term of this sequence that is not an integer. 43 is a Heegner number. 43 is a repdigit in base 6 (111). 43 is the largest natural number that is not a (original) McNugget number. This is the smallest prime number expressible as the sum of 2, 3, 4, or 5 different primes: *43 = 41 + 2 *43 = 11 + 13 + 19 *43 = 2 + 11 + 13 + 17 *43 = 3 + 5 + 7 + 11 + 17. The date magic square at right illustrates the magic constant as the sum of four primes: When taking the first six terms of the Taylor series for computing e, one obtains :$\backslash sum\_^\backslash frac=\backslash frac=2+\backslash frac,\backslash$ which is also five minus the fifth harmonic number. Every solvable configuration of the Fifteen puzzle can be solved in no more than 43 multi-tile moves (i.e. when moving two or three tiles at once is counted as one move).〔("The Fifteen Puzzle can be solved in 43 "moves"" ).
