Section 7.1.2 says:

Parameters a and b take the following values in this example:

   a = 7
   a = 0x7

   b = 43308876546767276905765904595650931995\\
   942111794451039583252968842033849580414

   b = 0x5FBFF498AA938CE739B8E022FBAFEF40563\\
   F6E6A3472FC2A514C0CE9DAE23B7E

It should say:

Parameters a and b take the following values in this example:

   a = 57896044618658097711785492504343953926\\
   634992332820282019728792003956564821034    (-7 mod p)

   a = 0x8000000000000000000000000000\\

Notes:

The elliptic curve coefficient 'a' in section 7.1.2 is incorrectly defined, with the result that the generator point P in section 7.1.5 fails to satisfy the congruence relationship (1) in section 5.1.

The mistake emanates from the appendix in the GOST R 34.10-2001 standard.

Defining a to be ( -7 mod p ) restores consistency, at least to the extent that the generator point P lies on the specified curve.
