Just flip a coin once to decide whether to promote only the even ones or only the odd ones.

The odd spins live on the odd-checkerboard lattice positions, and the even ones on the even-checkerboard.

And instead of striking out any number, let us write a "1" next to the odd numbers and a "0" next to the even ones.

I think the B's in the odd-numbered units are more attractive somehow than in the even ones.

Eight cards with numbers (1 through 8, odd numbers considered to be one dark color and the even ones as a different light color) are shuffled.

For the next range, from 253 to 254, everything is multiplied by 2, so the representable numbers are the even ones, etc.

Like a TV camera, it scans the image twice, first acquiring the odd lines and then starting from the top again and filling in the even ones.

It uses the predicted odd samples to prepare the even ones (or vice versa).

This step tries to predict odd samples taking into account the even ones (or vice versa).

"I'll flash the even ones, commissioner."
