Presentation

minimal degreeμ(G) = 22
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 22 points:

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

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

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