COMMENTS

Is the real number 3.611381... irrational? Transcendental?

LINKS

Table of n, a(n) for n=0..103.

FORMULA

Pi = 3, 1, 4, 1, 5, 9, 2, ...

Phi = 6, 1, 8, 0, 3, 3, 9, ...

so we get 3, 6, 1, 1, 3, 8, 1, ...

PROG

(PARI) \\ piphi alternating between Pi and Phi digit sequence

\\ piphi.gp Pi and phi digits merged

{ piphi(n) = default(realprecision, 10000); p = Pi/10; e = (sqrt(5)-1)/2; default(realprecision, 28); forstep(x=1, n, 2, d = p*10; d1=floor(d); p = frac(d); d2 = e*10; d3 = floor(d2); e = frac(d2); print1(d1" "d3" "); ); }
