76 So, the size of this table's data is 25 * 5 = 125 bits = 15.625 bytes.
80 Bitmap table is a Bit table with one column, that doesn't have 32-bits limitation for the width.
86 The first four bits determine the variable length of the encoded number:
87 - Values 0..11 represent the result as-is, with no further following bits.
88 - Values 12..15 mean the result is in the next 8/16/24/32-bits respectively.
