Presentation

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

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

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

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