Presentation

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

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

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