Presentation

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

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

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

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

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