Colorability conjecture for cyclic pseudo-Loupekine graphs with parity conditions

Let SS be a Loupekine 5-pole, let x{α,β}x\in\{\alpha,\beta\}, and let Sx(m;a,a,c)S_x(m;a,a,c) denote the associated cyclic pseudo-Loupekine graph. Assume that m/gcd(m,a)m/\gcd(m,a) is even and m/gcd(m,c)m/\gcd(m,c) is odd. Cyclic pseudo-Loupekine colorability conjecture. All such graphs Sx(m;a,a,c)S_x(m;a,a,c) are 3-edge-colorable. This conjecture concerns a broad generalization of Loupekine's construction; the supplied text gives no resolution or partial proof.
