Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 28 points:

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