Presentation

minimal degree	μ(G) = 22
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 7 generators on 22 points:

(8,13)(11,14)(15,16)(17,18)(19,21)(20,22);(7,8)(9,14)(10,11)(12,13)(15,17)(16,19)(18,22)(20,21);(4,6)(7,9,12,10)(8,11,13,14)(15,18,20,19)(16,17,22,21);(3,4)(5,6)(7,9,12,10)(8,11,13,14)(15,17)(16,18)(19,22)(20,21);(7,10,12,9)(8,11,13,14)(15,18,20,19)(16,17,22,21);(7,11)(8,9)(10,13)(12,14)(15,19,20,18)(16,21,22,17);(1,2)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((8,13)(11,14)(15,16)(17,18)(19,21)(20,22), (7,8)(9,14)(10,11)(12,13)(15,17)(16,19)(18,22)(20,21), (4,6)(7,9,12,10)(8,11,13,14)(15,18,20,19)(16,17,22,21), (3,4)(5,6)(7,9,12,10)(8,11,13,14)(15,17)(16,18)(19,22)(20,21), (7,10,12,9)(8,11,13,14)(15,18,20,19)(16,17,22,21), (7,11)(8,9)(10,13)(12,14)(15,19,20,18)(16,21,22,17), (1,2));
