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