COMMENT
|
A floretion-generated sequence which may be seen as the result of a certain sequence transform applied infinitely often. For a related case, see "Generalized Sequence Convergence?" link. This sequence is one of three related sequences, the others being A104771 and A104769.

FORMULA
|
a(n+3) = a(n) - a(n+2); a(0) = 1, a(1) = -1, a(2) = 2; a(n+1) - a(n) = ((-1)^(n+1))*a(n+5); a(n) = A104771(n) - A104769(n)

PROGRAM
|
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)-jesleftfor[A*B], ForType: 1A.
