In the book Applied Physics by P.K.Mittal, on page#25 under the heading of "Bravais lattice in two dimensions", a paragraph says,
"The number of point groups in two dimensions is 10."
My 1st question is,
Then how many in three dimensions?
Paragraph further says,
"10 groups in two dimensions produce only 5 Bravais lattice."
What is meant by above statement?
