WebSo I wrote. Theorem: A5 is simple. To show: A5 has only A5 and {Identity} as normal groups. Proof: The number of elements in An is n! 2, so A5 = 60 = 22 ⋅ 3 ⋅ 5. The 3- and 5- Sylowgroups are isomorph to Z / 3Z and Z / 5Z, so they are cyclic. With the Sylow-theorems we know that:

Web1.0 x 1.5 in: To obtain paper sizes in centimetres, convert mm values to cm by dividing by 10 and in feet by dividing inch values by 12. More units here and sizes in pixels here. 4A0 & 2A0 - The DIN 476 Oversize Formats. The paper sizes bigger than A0, 4A0 & 2A0, aren't formally defined by ISO 216 but are commonly used for oversized paper. WebThus the only possibility is N = 1 or N = 60 which proves that A5 is simple. The idea of this proof is due to Joseph Gallian. He treats the case N = 2 differently, but the proof is essentially the same as the one here. You can also use the same method to prove that PSL(2, 7) is simple.
