COMMENTS

A floretiongenerated sequence.


LINKS

Table of n, a(n) for n=0..60.
Index entries for linear recurrences with constant coefficients, signature (1,0,1).


FORMULA

Recurrence: a(n+3) = a(n)  a(n+2); a(0) = 1, a(1) = 2, a(2) = 3.
a(n+1)  a(n) = ((1)^(n+1))*a(n+5); a(n) = A104769(n) + A104770(n).


PROG

Floretion Algebra Multiplication Program, FAMP Code: Define A = + .5'i + .5'j + .5'k + .5e and B = + .5'i + .5i' + .5'ii' + .5e. Then (a(n)) = jesloop(infty)jesfor[A*B], ForType: 1A.
