Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 28 points:

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