  In the present paper, authors study the strange stars with the MIT Bag EoS
admitting Buchdahl symmetry (non-singular and physically viable metric
potential) in the both linear $f(Q)=aQ+b$ and non-linear $f(Q)=Q+aQ^b$ forms of
modified symmetric teleparallel gravitation. In order to obtain the correct
form of Buchdahl metric coefficients, they matched interior strange star
spacetime with the exterior Schwarzschild vacuum spacetime. As a strange star
candidate, PSRJ1416-2230 has been used with mass $M=1.69M_\odot$ and radius
$R=9.69R_\odot$. For either linear and non-linear $f(Q)$ gravities, they probed
Null, Dominant and Strong Energy Conditions as well as the radial, tangential
Equation of State (EoS), gradients of the perfect fluid energy-momentum tensor
elements, Tolman-Oppenheimer-Volkoff equilibrium condition, relativistic
adiabatic index and causality conditions, surface redshift. It was found that
strange stars in the linear and non-linear $f(Q)$ gravity show physically
viable behavior, respect energy and causality conditions, has EoS in the bounds
$0\leq\omega\leq1$ and surface redshift does not exceed 2, as expected.
