Presentation

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

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

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