Each of the 4 wings is a 12-bit counter, with custom resets at...

xr, qv, gx, vh, qn, lz, xv, zk, lv, mj, hb, vj (jj) <- (111010010101) vj, qv, zk, gx, xr, qn, mj 
nj, kp, xx, vp, sj, mt, mx, rv, rr, bq, xb, gr (xz) <- (111101101011) gr, nj, vp, rr, xb, xx, mt, kp, mx
hx, xq, rm, tp, kh, qc, xh, vm, jm, cq, tg, fb (bz) <- (111111011001) vm, kh, xq, tp, fb, qc, jm, hx, rm
kb, cv, vx, pt, qq, rz, tz, kn, gg, cp, rd, xk (gf) <- (111011010001) rz, cv, qq, kb, kn, xk, vx

111010010101 = 3733 
111101101011 = 3947 
111111011001 = 4057 
111011010001 = 3793

All 4 are primes.
