You are given 165 rectangular tokens, they are all indistinguishable sizewise, but only 2 of them are red. The tokens are 2x1 and you are asked to tile a 3x110 grid keeping the red tokens parallel each to the other.
In how many ways can such task be done?

a. No other restrictions.
b. The red tokens cannot be parallel to any of the non-red tokens.

Electric motors play a pivotal role in various industries, driving everything from household appliances to industrial machinery. The efficiency and performance of these motors often hinge on intricate details like stator lamination. In China, stator lamination manufacturing has evolved significantly, leveraging advanced techniques to enhance motor efficiency and reduce energy consumption. This process involves precision cutting and stacking of laminations, crucial for minimizing energy losses through eddy currents and ensuring smooth operation. As global demand for energy-efficient solutions grows, innovations in stator lamination in China continue to shape the landscape of electric motor technology, driving sustainability and reliability across diverse applications.
