The Doctor doesn't like to travel through space and time alone - figure out who these companions are then take the answers and assign numerical values to the letters in the typical fashion, A=1 Z=26. Then for each group add all the numerical values together and plug your results into the formula listed below.

North: Posted Coords Minutes + (Group N)/1000

Remember to record the Gallifrey symbols found in the log book, they are needed to determine the coordinates of the bonus cache of this series. After conversion, 29 are labeled North and 29 are labeled West followed by a number. The bonus cache, The Best Idea Ever Invented, provides the instructions how to determine its coordinates.
