alg_poly_orbit_legendre_v1_1218484723_3270
A cryptographic protocol uses a function $f(x) = 3x^4 + 3x^3 - x^2 - 5x - 5 \bmod 29$ and exponentiation modulo 29. Starting with a seed $a$, it computes $N = a^{14} \bmod 29$, then $M = f(a)$, $R = M^{14} \bmod 29$, and $S = N + R$. Then it computes $T = f(M)$. A seed is valid if $T = a$, $S$ is divisible by 3, and $M...

A robot computes three values from sensor inputs: it multiplies 128 by 111 and adds 77 times -89, taking the absolute value to get $M$. Then it computes $R$ as the sum of GCDs from differences in signal strengths: $\gcd(128,89)$, $\gcd(|128-77|, |111-89|)$, and $\gcd(77,111)$. It then calculates $S = (M + 2 - R)/2$. Wh...
