Morpion Solitaire - Infinite Records Grids (4T and 4D games)

In the 4T and 4D games, the initial pattern is a cross using 24 dots. But is it possible to get a better score than the records of 62 moves (4T) and 35 moves (4D) from another initial pattern using the same number of dots (24)?

Yes, and the score can even be infinite! In fact, only 7 dots well placed are sufficient, as proved by this figure.
