Two-dimensional derivative lattices of indices 2 to 7

The entry for each derivative lattice starts with a running number which is followed, between parentheses, by the appropriate basis-vector relations.

Index 2	$[1(2{\bf a}, {\bf b});\ 2({\bf a}, 2{\bf b});\ 3(2{\bf a}, {\bf b} + {\bf a})]$
Index 3	$[1(3{\bf a}, {\bf b});\ 2({\bf a}, 3{\bf b});\ 3(3{\bf a}, {\bf b} + {\bf a});\ 4(3{\bf a}, {\bf b} - {\bf a})]$
Index 4	$[1(4{\bf a}, {\bf b});\ 2({\bf a}, 4{\bf b});\ 3(4{\bf a}, {\bf b} + {\bf a});\ 4(4{\bf a}, {\bf b} - {\bf a});\ 5(4{\bf a}, {\bf b} + 2{\bf a})]$ ;
	$[6(2{\bf a}, 2{\bf b} + {\bf a});\ 7(2{\bf a}, 2{\bf b})]$
Index 5	$[1(5{\bf a}, {\bf b});\ 2({\bf a}, 5{\bf b});\ 3(5{\bf a}, {\bf b} + {\bf a});\ 4(5{\bf a}, {\bf b} - {\bf a});\ 5(5{\bf a}, {\bf b} + 2{\bf a});]$
