101
There are 74 of them, and I am not about to list them.
Go through the numbers: remove 1 and all 25 prime numbers. You will be left with the 74 composite (rectangular) numbers.
rectangle numbers from 1-100

There are uncountably infinitely many real numbers between 1080 and 1100. There are 21 integers between 1080 and 1100, including the "endpoints." They are: 1080, 1081, 1082, 1083, 1084, 1085, 1086, 1087, 1088, 1089, 1090, 1091, 1092, 1093, 1094, 1095, 1096, 1097, 1098, 1099, 1100.

The second and third rectangular numbers are 6 and 12
There is no such formula. Rectangular numbers are composite numbers and there is no known formula that will generate either composite numbers or prime numbers.
8924 is the number that comes 1100 numbers after 7824.
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.
1000, 1020, 1040, 1060, 1080, and 1100

26,200 - 1,100 = 25,100
20 and 30 are rectangular numbers (4 * 5 and 5 * 6). There are none in between them.

1111 is the only one.

4, 6, 8, 9, 19
Since all the numbers in that range start with "11", there is really only one option!
The second and third rectangular numbers are 6 and 12
