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