Let us look at q equal to 2 squared which is 4, this is not prohibited right from the lemma, we do not know if there is a field like this or not, but it is not excluded by the lemma, so is there a field of order 4? So, what we do is certainly we cannot at Z mod 4 Z because Z mod 4 Z is not a field, we cannot take Z mod p Z for any prime because Z mod p Z as order p.
हम देखते हैं की q = 22 जो कि 4 है , यह लेम्मा से निषिद्ध नहीं है | हमें यह पता नहीं है कि ऐसा फील्ड है कि नहीं, लेकिन यह लेम्मा से छोड़ा हुआ नहीं है , तो क्या 4 आर्डर का कोई फील्ड है?
