REMARK 1: The problem is described in [Gar3], "New Mathematical Diversions", instead of [Gar1].
REMARK 2: 3x4 matrix would also be appropriate for the example.

REMARK 3: The function diag is not defined. (It defines a diagonal matrix with the given entries on the diagonal.)
REMARK 4: The matrices on right hand side of the equation should be swapped.

REMARK 5: F_5^X is not defined.

REMARK 6: The term is not explained in this book. See transvection on Wikipedia, for example.

REMARK 7: f_V is defined to be the map F_V(g)=g_V.

REMARK 8: the notation is not defined.







The typo mentioned above on page 46 was caught by Greg Ives - thank you! The typo mentioned above on page 231 was caught by Michael Burns - thank you! The errata mentioned above on page 255 (the statement of Claim 1 is so vague it has no meaningful mathematical content) was caught by Prof. Juergen Voigt - thank you! I think Haruyuki Kawabe for the remaining typos, as well as his Japanese translation of the book. - David Joyner
