Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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