Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 256

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

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

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

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