p. 14 Exercise 1.12: µ(n1, n2) = µ(n1)µ(n2) if n1, n2 are relatively prime.
p. 24, line 12, insert: In case an isomorphism exists from G1 to G2, we say "G1 is
isomorphic to G2" and write G1 G2.
p. 45 line 5:
(, )
1 ... n n+1 ... 2n
1 ... n (n+1) ... (2n) .
p. 47, insert after theorem 7.2:
Of course one could throw in redundant generators (such as e), and on the
other hand one could tack on direct products with copies of {e}, since any group
G G × {e}, and it will be convenient to permit these redundancies.
p. 52 line 12:
ker f C1(p) × · · · × Ct(p),
p. 58 line 5: 0 i < o(a), 0 j < G
