Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 28 points:

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