What was the largest pengos note Hungary made in 1946 even though it never circulated?

The denominations milpengo (one million pengo) and bilpengo (short: b.-pengo, one trillion (1000000000000) P) were used to simplify calculations, cut down the number of zeros and enable the reuse of banknote designs with only the color and denomination name changed.

The hyperinflation was so out of control that at one stage it took about 15 hours for prices to double and about four days for the pengo to lose 90% of its original value.
