 FACT: Scully and Mulder use Napiers Constant (also known as Eulers  Number) to gain access to locked doors using an electronic keypad at  an abandoned mine. Mulder checks with Scully that Napiers Constant  is in fact "27828" and she confirms that it is. However, the  constant is NOT 27828, it is actually 271828 (or 2.71828...).  Without the number "1" in the sequence, Scully and Mulder should not  have been able to enter any of the doors.
