A bicirculant is a regular graph that admits an automorphism having two vertex-orbits of the same size. A bicirculant can be described as follows. Given an integer m≥1m \ge 1 and sets R,S,T⊆ZmR, S, T \subseteq \mathbb Z_m such that R=−RR=-R, T=−TT=-T, 0∉R∪T0 \not\in R \cup T and 0∈S0 \in S, the graph B(m;R,S,T)B(m;R,S,T) has vertex set V={u0,…,um−1,v0,…,vm−1}V=\{u_0,\dots,u_{m-1},v_0,\dots,v_m-1\} and edge set $E={u_iu_{i+j}| \ i \in\mathbb Z_m, j \in R} \cup {v_iv_{i+j}| \ i \in\mathbb Z_m, j \in T} \cup{u_iv_{i+j}| \ i \in\mathbb Z
