Reported by Jon:

Only three of the team (Jon, Tav, and Nick) were available on a cold December evening. However, the team set off determined to prove that the current dig can be worked by only three. The trip through the cave was an opportunity to warm up. There has been little rain and the cave remains dry.

At the dig face, Jon dug and filled buckets, Nick hauled and Tav emptied.

No onward development was made; effort focused on clearing out the approach to the dig face.

Tav counted the buckets, so we have a reliable number. 26 buckets were filled, hauled and emptied. There was much discussion as to whether or not this was a good number. Tav prefers even numbers and had a preference to stop at a satisfactory two dozen. Nevertheless he would have accepted 25 (as a quarter of 100) or 27 (apparently lucky). Nick just wanted to sneak in a couple of extras (and did so). Jon prefers odd numbers and ideally prime ones. We settled on 26, because of time constraints or, indeed, overtime. The good news is that 26 is 2 times 13, both of which are prime.

However, the number of the evening was 3. The dig can be worked with 3.
