Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 7 generators on 28 points:

(2,4)(6,9)(7,11)(14,17)(15,19);(1,2)(3,4)(6,9)(7,11)(21,22)(23,26)(24,27)(25,28);(21,23)(22,25)(24,28)(26,27);(6,9)(7,11)(14,17)(18,20);(6,9)(10,12)(14,17)(18,20)(21,23)(22,26)(24,28)(25,27);(5,6,8,9)(7,10,11,12)(13,14,16,17)(15,18,19,20)(21,22)(23,25)(24,27)(26,28);(5,7,8,11)(6,10,9,12)(13,15)(14,18)(16,19)(17,20)(21,22)(23,25)(24,27)(26,28)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
