Properties

Appears in sequences

• Tribonacci numbers: a(n) = a(n-1) + a(n-2) + a(n-3) with a(0)=a(1)=a(2)=1.at n=23A000213
• Consider all quadruples {a,b,c,d} which reach {k,k,k,k} in n steps under map {a,b,c,d}->{|a-b|,|b-c|,|c-d|,|d-a|}; look at max{a,b,c,d}; sequence gives minimal value of this.at n=33A045794
• Primes in the tribonacci sequence A000213.at n=8A056816
• Minimum value t such that all quadruples of Diffy_length >= n have a maximal value >= t.at n=35A065678
• Prime differences of tribonacci numbers.at n=28A113239
• Hilltop maps: number of n X 2 binary arrays indicating the locations of corresponding elements not exceeded by any horizontal or antidiagonal neighbor in a random 0..1 n X 2 array.at n=10A221440
• Frobenius-Perron dimensions of simple integral fusion rings of rank 4.at n=10A369625
• Prime numbersat n=43984
