Here is the last octet binary for your range of numbers.
Note that only the 128, 64, and 32 bit value positions do not change, and are always 001 (32). If you use a mask of 0.0.0.31 to "don't care" the changing bits, you get a range of 32-63 for your summary. So a single summarization exceeds your range.
If you move two more bits right with the must match position (00101 or 40) the remaining 3 "don't care" bits mask 0.0.0.7 give you a range of 40-47. This is closer, but you still need 48 and 49.
The 48-49 range can be matched with a 0.0.0.1 mask.
