so, in short, one market maker agreed a price for the entire lot, then notified the market of the intention to put the whole lot through in small lots, rather than one hit, to avoid trashing the price by alerting the market. Once the market maker had finished the job, the market was notified and the trade disclosed.
you will note that this is usually done at a discount to the prevailing prices - I could buy at 3p then, so there is the possibility that someone has actually been buying at the bid here.
