Presentation

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

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

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