"120PH (peta hashes) at the time, equivalent to around 0.12 EH (exa hashes), with an average of around 12PH over a week. This hash rate was roughly 0.02% of the total network hash rate."

Kolivas analyzed the block-solve summary and speculated that this large miner had either recently transitioned from pooled mining post-halving, likely due to no longer covering their electricity costs for pooled mining, in pursuit of a chance at a solo block. Alternatively, they may have been intermittently hashing or renting large amounts alone.
