Presentation

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

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

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